TRACK-SANDING APPARATUS.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed April 29, 1908. Serial N 0. 430,008.

To all whom it may concern:

Be it known that I, ISAAC A. GIBBS, a cltizen of the United States,residing at Roanoke, in the county of Roanoke and State of Virginia,have invented certain new and useful Improvements in Track-SandingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements intrack-sanding apparatus and particularly of that type in which the pipeor conduit through which the sand is conveyed to the track rail passesthrough a vertical passage in the brake-head to which the brake-shoe isconnected, and is independent of the same, and consequently while thethrust-block and brake-shoe are movable toward and from the wheel of thelocomotive while the sand pipe or conduit being secured in position atits upper extremity occupies a substantially fixed position withreference to the brake-head and track-rail the said pipe or conduitdelivers the sand always at the same distance from the wheel. It is alsoliable to injury resulting from contact with the thrust block during thevibrations of the latter.

My invention has for its object to overcome the disadvantagesreferred toand to provide a sanding apparatus adapted to de liver the sand at apoint much nearer the wheel and to move toward and from the wheelcoincidently with and to the same extent as the movement of the brakeshoe.

With these ends in view my invention consists in the combination withthe brakehead and brake-shoe, of a sand delivery pipe or conduit,detachably connected with the brake-head all as will be hereinafter morefully explained.

In order that those skilled in the art to which my invention appertainsmay know how to make and apply my improved track sanding apparatus andappreciate its advantages I will proceed to describe the same referringto the accompanying drawing in which Figure 1 is a side elevationshowing my improvement in its relation with a brakehead and brake-shoe,and adapted for connection with the sand dome of a locomotive.

Fig. 2 is a central vertical section of the same. Fig. 3 is a transversesection on the line ab of Fig. 2, and Fig. 4 is a front elevation of thesand conduit removed from the brake-head.

Similar numerals represent like parts in the several figures of thedrawing.

1, is an ordinary brake-head adapted to be pivoted by a bolt to abrake-beam.

2, is a brake-shoe secured to the brakehead by a screw bolt 3, or in anyother suitable manner.

4, is a sand conduit preferably composed of cast metal and having itsupper extremity flared or of hopper shape in order that it may receivethe end of a discharge pipe 6, leading from the sand dome, or if desiredthe upper end of the conduit 4, may be connected with the sand dome byany suitable flexible connection. The conduit 4, at its lower extremityis curved toward the brake shoe as clearly illustrated at Fig. 1, and maif preferred be provided with a flexible foot piece 7, in order that thesand passing through the conduit may be delivered close to the point ofcontact between the wheel and rail.

At a point above the locality of the screw bolt 3, which secures thebrake-shoe to the brakehead the conduit 6, projects as shown at 9, toconstitute a bearing surface for a suitable set screw or bolt 10, bywhich the conduit is held in fixed relation with the brake-head 1, toprevent vertical or vibrative movement of the conduit with respect tothe same.

The sides of the conduit are formed flat to lie between and to contactwith ribs 12, on the interior of the brake-head inorder that no sidewisemovement of the conduit with reference to the same can take place, sothat when the conduit has been secured in position by the set screws orbolts 10, it bears a fixed and practically integral relation with thebrake-head and brakeshoe and vibrates with the same.

It will also be apparent that the conduit 6, may be readily removed whennecessary or desirable, by first releasing the brake-head 1, from thebrake-beam and then loosening the set screw 10, whereupon the brake-headis free to be removed in a rearward direction.

The conduit 6, may be cast integral or if desired it may be cast in twoparts as indicated by the line 0 Z in Fig. at, secured together byscrews 11, or in any other desired manner.

\Vhile 1 have shown and described the sand conduit as provided with aflexible float secured thereto and may prefer this construction, as onemeans of directing the sand close to the point of contact between thewheel and the rail, it will be obvious that inasmuch as the brake-headand sand conduit are secured in fixed relation with one another andmustneeessarily move as a unitary structure. the lower extremity of the1 conduit may be extended and curved for- I \vardly to any desiredextent without in any manner effecting the movement of the brakehead andbrake-shoe or subjecting the sand conduit to damage.

From the construction shown and tie scribed it will be readilyunderstood that my improved sanding apparatus is extremely simple andeconomic of construction and readily applied and removed when necessary.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In a track sanding apparatus, in coml I bination with the brake headadapted to be 1 secured to the brake shoe and brake beam j and itorniedwith a central vertical passage and open rearwardly, a sand conduitlocated within the open passage in the brake-head and removably securedtherein by set screws in each side of the brake head, substantially ashereinbefore set forth.

2. in a track-sanding apparatus such as described. a sand conduitcomposed of two longitudinal sections separably secured toj gether, andremovably secured in a fixed relation with the brake head, substantiallyas hereinbefore set forth.

In a track-sanding apparatus such as described, a sand-conduit locatedwithin the brake-head and removably secured in fixed relation with thebrake head, and provided with a flexible foot extension, substantiallyas hereinbefore set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
